I've been asking and looking around on the web to determine if using a magnetic mount could mess with my RD. I've seen a lot of opinions, guesses, alternative approaches, and other well-meaning, but ultimately useless observations - but no real useable info.
I'm a technical guy (an honest-to-God engineer) but I am not an RF engineer, however, I have a network buddy who is an RF engineer ...
I asked him recently if using the new rare earth magnets in lieu of suction cups to mount a RD would adversely impact my STi Driver's performance.
The answer was NO.
A magnet might adversely impact magnetic based memory, but there's no issue with a modern RD.
So, feel free to use the new strong magnets to mount your RD.
